Abstract
A process for direct esterification of an alkyl aldehyde with an alkyl alcohol to produce an alkyl ester is disclosed. The process comprises reacting an alkyl aldehyde with an alkyl alcohol in the presence of an Au/TiOa catalyst, a base and an enal or oxygen to form an ester and an aldehyde. The process avoids liberation of water and avoids the step of oxidation of the alkyl aldehyde to an alkyl acid.
